Chapter 15.02 - DRAINAGE AND SUBSURFACE WATER CONTROL
Part of the Code of Ordinances of South Salt Lake, UT.
The text
15.02.010 - Purpose.#
A.
The City, by and through its City Council, recognizes that the tremendous increase in property development has a significant impact on surface water runoff, both in terms of quantity and quality.
B.
The City is in need of a method and procedure whereby it can provide for and control surface water runoff, so as to protect the persons and property both within and without the corporate boundaries of South Salt Lake City.
(Ord. No. 2020-02, § III(Exh. B), 1-8-2020)

"Drainage plan" means a plan showing all drainage facilities, both on- and off-site, designed to carry all surface and subsurface waters from a subdivision or development.
"Subdivision" means any residential development of over one lot concurrently, or any development (including one lot) which will cause a significant change in the existing drainage pattern.
(Ord. No. 2020-02, § III(Exh. B), 1-8-2020)

(Ord. No. 2020-02, § III(Exh. B), 1-8-2020)
15.02.060 - Drainage plan.#
Prior to approval of the development or subdivision by the City engineering department, a drainage plan shall be prepared at the expense of the developer or subdivider, by a qualified and licensed engineer. The plan shall include a complete analysis of all surface drainage and subsurface drainage patterns and the impact that the proposed project will have upon them; including plans showing, in detail, proposed construction designs for handling of drainage.
(Ord. No. 2020-02, § III(Exh. B), 1-8-2020)
15.02.070 - Fees.#
The developer, subdivider, or owner shall, prior to being granted any permits whatsoever, pay a fee which shall be determined by the formula in Section 15.02.080. Said formula shall determine the cubic feet of runoff per second which is attributable to the proposed development. The fee shall be assessed at a rate set by resolution of the City Council per cubic foot per second additional runoff created on the proposed development or subdivision.
(Ord. No. 2020-02, § III(Exh. B), 1-8-2020)
15.02.080 - Determination of fee (formula).#
The amount of surface water runoff shall be established by using the following tables and formula: A.
Rainfall Factor: The fee shall be assessed on the basis of 1.4 inches of rainfall per hour (which is the acceptable one-hundred-year standard). This shall be known as factor A in the formula.
B.
Area Factor: The rainfall factor shall be multiplied by the number of acres in the development or subdivision. This factor shall be known as factor B in the formula.
C.
Land Use Factor:
1.
The following table shall be used to determine the runoff from various types of development:
General Land Use Classification Runoff Coefficients
Undeveloped 0.15
Residential:
Single-family 0.35
Two-family 0.45
Multiple-family 0.60
Suburban estates 0.25
Commercial:
Neighborhood 0.60
General 0.80
Drive-in movies 0.70
Industrial:
Light 0.60
Heavy 0.80
Agriculture 0.15
Institutional 0.30
Parks and recreation: 0.20
Utilities and transportation 0.50
Streets 0.85
Vacant 0.15
Other: determined by City Engineer
2.
Differential runoff will be determined by evaluating the land use before the development C1 and after the development C2. The difference (C2 - C1) will be multiplied by the factors A and B to determine the additional runoff in cubic feet per second.
D.
The number of cubic feet per second of increased runoff caused by the proposed development shall be known as Factor f.
E.
The formula for determining the service fee for water runoff and storm drain shall be determined by the following formula:
A × B × (C 2 − C 1 ) = F
F × amount set by resolution of
the City Council = Service Fee.
(Ord. No. 2020-02, § III(Exh. B), 1-8-2020)
15.02.090 - Storm drain sumps and detention ponds.#
In the event there is no gutter or storm drain line existing within three hundred (300) feet of the property which is proposed to be developed, with adequate capacity to convey storm water as determined by the City Engineering Department, the developer or owner may be permitted to use a storm drain sump or detention pond upon approval of the City Engineering Department.
(Ord. No. 2020-02, § III(Exh. B), 1-8-2020)
15.02.100 - Catch basins requirement.#
In any new development whether residential subdivision, industrial park, multiple unit dwellings or otherwise, surface water will not be allowed to be carried in a gutter for more than seven hundred (700) feet without the installation of a catch basin or other device for depositing the surface water into the storm drain system.
(Ord. No. 2020-02, § III(Exh. B), 1-8-2020)
